Abstract

In this study, the distribution of plasma-functionalized multi-walled carbon nanotubes in polyacrylonitrile nanocomposite fibers produced by wet spinning method using different surfactants (Triton-X and sodium dodecyl sulfate) was investigated. Firstly, we produced CNTs by chemical vapor deposition (CVD) technique. Secondly, low-pressure plasma functionalization of CNTs was realized. Finally, nanocomposite polyacrylonitrile fibers doped by CNTs were obtained using wet spinning technique. Properties of produced carbon nanotubes, functionalized carbon nanotubes and nanocomposite polyacrylonitrile fibers were examined by the analyses of chemical composition, surface structure, structural and mechanical properties.

Plazma ile İşlem Görmüş Karbon Nanotüp Üretimi ve Farklı Yüzey Aktif Maddelerle PAN Lif Çekim Çözeltisinde Dağılımı

Abstract

Bu çalışmada plazma ile fonksiyonelleştirilmiş karbon nanotüplerin farklı yüzey aktif maddeleri kullanarak (Triton-X ve sodyum dodesil sülfat) yaş çekim yöntemi ile üretilen poliakrilonitril nanokompozit liflerinin içerisindeki dağılımı incelenmiştir. İlk olarak, karbon nanotüpler kimyasal buhar biriktirme yöntemi ile tarafımızdan üretilmiştir. Ardından karbon nanotüplerin düşük basınç plazma ile fonksiyonelleştirilmesi gerçekleştirilmiştir. Son olarak, yaş lif çekim yöntemi ile karbon nanotüp katkılı nanokompozit poliakrilonitril lifleri elde edilmiştir. Karbon nanotüplerin, plazma ile fonksiyonelleştirilmiş karbon nanotüplerin ve nanokompozit poliakrilonitril liflerinin özellikleri, kimyasal kompozisyon, yüzey yapısı ve yapısal - mekanik özelliklerin analizleri ile incelenmiştir
